PATENT IRA L. BOYER, OF WHEATON, KANSAS.

CU LTlVATO R.

SPECIFICATION forming part of Letters Patent No. 621,894, dated March 28, 1899.

Application filed January 10 1899- Serial No. 701,738. (No model.)

T0 to whom, it may concern:

Be it known that I, IRA L. BOYER, a citizen of the United States, residing at Wheaton,-in'

exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to cultivators and it consists in the novel construction and combination of the parts hereinafter fully described and claimed.

In the drawings, Figure l is a longitudinal section through the cultivator. Fig. 2 is an end view of the axle and portions of the'cultivating mechanism. Fig. 3 is a sectional plan view taken on the line 00 5c in Fig. 2 and showing one of the shovel-cultivator beams.

A is an axle having square portions (1 near each end, and B are the ground-wheels, j ournaled on theend portions 1) of the axle. The

middle portion 0 of the axle consists of a slidable frame provided with uprights c, which are slidable vertically in dovetailed or recessed slots in the uprights c, which project from the square portions'a of the axle. The uprights c and c are provided with holes, and b are bolts for securing the uprights together after the position of the frame 0 has been adjusted by sliding it vertically to suit the height of the corn.

Two similar clamps D are slidable longitudinally upon the square portions a and are provided with bolts 61 for clamping them to the axle after their positions have been adjusted.

The beam of each plow or shoveLcultivator has a forked front part E, which is pivoted to one of the clamps D in front of the axle by a vertical pin c. Each beam also has rear portions E, the front ends of which are pivoted to the part E by a horizontal pin 6. The rear end portions of the parts E are curved downward and are provided with plow-blades or cultivator-shovels f of any approved construction. A toothed segment F-is formed on the rear end of each part E concentric with the pin e, and f are distance-pieces for securing the parts E together. The segment F is provided with a curved slot for one of the dis tance-pieces to pass through.

.G is the guiding-handle for each shovelcultivator, secured to the rear distance-piece f and to a bracket g.

H is a retractable spring-pressed catch carried by the shank of the handle G and engaging with the teeth of the segment F. A lever g is pivoted to the handle, and h is a rod which connects the lever with the catch, so

that it can be worked without letting go the handle.

I are similar draft-arms mounted on the ends of the axle adjacent to the ground-wheels and connected to the uprights c by braces 2'. When the shovel-cultivators alone are used, the horses or other animals are attached to the arms I and the frame 0 is slid up high enough to clear the tops of the corn or other plants which are being cultivated.

J is a removable tongue secured to the middle part of the frame 0 by bolts j. This tongue forms the draft attachment for the implement when the corn is very young and the disk cultivator is used in addition to the shovelcultivators.

K is a frame which depends from the rear end of the tongue J, and 7c is a block which is slidable vertically in the frame K, which forms a guide for it.

M are cultivator-disks mountedon a shaft m, carried by the block 70.

M is a stay which supports the frame K from the middle part of the tongue.

N is a notched quadrant "carried by the tongue above the frame K, and n is a lever pivoted to the quadrant N and provided with a catch at for engaging with the quadrant.

O is a rod pivot-ed to the lever a and to the block 70. The vertical position of the cultivator-disks is adjusted by means of the lever n.

The cultivator-disks are arranged-between the shovels and a little in front of them, so as to prevent clods thrown up by the shovels from falling againstthe young plants. These cultivator-disks cultivate the ground close to the roots of the young plants and cut oi the Weeds.

When the plants are partly grown, the tongue and the cultivator-disks are removed,

and the implement is transformed into a tongueless cultivator.

\Vhat I claim is 1. In a cultivator, the combination, with a forked front portion E of a beam having a vertical pivot-pin e, and a toothed segment F at its rear end; of two rear portions E pivoted to the portion E by a horizontal pin 6 and provided with blades f at their rear parts, a

guiding-handle secured between the two said portions E behind the toothed segment, and a retractable catch carried by the said handle and engaging with the said segment, substantially as set forth.

2. In a cultivator, the combination, with an axle, and a clamp secured thereto; of a beam formed of front and rear parts E and E, the front part E being forked and pivoted to the clamp by a vertical pin and provided with a toothed segment, and the rear parts E being arranged one on each side of the part E and coupled. together by distance-pieces, a horizontal pin pivoting the parts E to the part E, cultivator-shovels carried by the parts E, a guiding-handle secured to the parts E, and a retractable catch carried by the said handle and engaging with the said segment, substantially as set forth.

3. A cultivator comprising an axle mounted on wheels and provided with a verticallyadjustable middle portion, cultivator-beams provided with shovels and attached to the end portions of the axle, draft-arms carried by the end portions of the axle, a removable draft-tongue attached to the middle portion of the axle, and cultivator-disks supported from the rear part of the said tongue between the said shovels, substantially as set forth.

4. In a cultivator, the combination, with an axle mounted on Wheels and provided with a vertically-adjustable middle portion, of clamps adjustable longitudinally on the end portions of the said axle, two similar cultivator-beams provided with front and rear parts E and E pivoted together and adjustable vertically, vertical pins pivoting the front parts E to the said clamps, shovels carried by the rear parts E, a draft-tongue attached to the said middle portion of the axle, cultivator-disks carried by the said tongue between the said shovels, and means for adj ustin g the said disks vertically, substantially as set forth.

5. Ina cultivator, the combination, with an axle mounted on wheels and provided with a vertically-adjustable middle portion, of a draft-tongue attached to the said middle portion of the axle, a frame depending from the rear part of the said tongue, a block slidablc vertically in the said frame, cultivator-disks supported from the said block, and means for adjusting the said block, substantially as set forth.

In testimony whereof I affix my signature in presence of two witnesses.

IRA L. BOYER.
